Full cell phone batteries are a rarity. Between answering emails, text messaging and sneaking in quick rounds of “Angry Birds,” cell phone chargers are normal additions to tote bags. Waiting hours for a phone to charge seems like death, especially when traveling, but a new invention may soon cut charging time down to 30 seconds.

Eesha Khare, 18, invented a fast-charging device called the supercapacitor. It is miniature energy-storing device that can juice a phone to full charge within 20-to-30 seconds.

“I developed a new supercapacitor, which is basically an energy storage device which can hold a lot of energy in a small amount of volume,” she told KPIX 5 in California.

Khare – a high school student from Saratoga Calif. – grew tired of never having a full battery, leading to this creation.

“My cellphone battery always dies,” she told NBC News. Creating the supercapacitor solved Khare’s issue and also piqued her interest in “really working at the nanoscale to make significant advances in many different fields.”

The high school senior is headed to Harvard University in the fall and she’s toting her invention with her. The supercapacitator received a huge boost at the 2013 Intel International Science and Engineering Fair where Khare won the Intel Foundation Young Scientist Award. She was awarded $50,000 – sure to come in handy at Harvard – and a chance to showcase her invention to potential investors.

Khare hopes her creation will “set the world on fire,” eventually having enough energy to power automobiles.

So far the burgeoning scientist has powered a LED, but she hopes a few tweaks can lead to the placement of the supercapacitor in cellphones and other technological devices. Khare wants to cut down our dependence on electrical outlets.

Long-lasting, quickly-charged phones could be viable assets to our futures.
